There are two common possibilities for this error:
1: The .ISO file was corrupted during download. Check the md5sum of the
.ISO file -- on another Linux system run "md5sum XXX.iso" and compare the
output to the md5sum reported on the page you downloaded it from.
2: The actual CD has a scratch or other imperfection (possibly invisible to
the naked eye). If the MD5sum is correct (#1 above), then re-burn the CD.
If the second fails, try re-burning the image at a slower speed and/or on a
different computer.

Another possiblity is that the CD drive in your server isn't reading the CD
properly. If you boot the CD on another system and run the check CD, does
it pass there?

Yup, if there is an error with the CD, then *any* error is possible.
